    Full text link
    Cloud computing is an interested and bigdeveloping computing technology that maintain dataservers and service huge applications to provide endusers in many different organization. Although cloudcomputing gives many benefits of service, but it canhardly accurate the requirements of end users inhumans’ daily lives. A new computing paradigmcalled Fog Computing which is an emerging as anecessary and popular computing paradigm toperform Internet of Things (IoT). Fog computing is amiddle layer of cloud and IoT. When fog computingis insufficient for the resource requirements of IoT,cloud computing can assist fog computing to get ahandle of intensive applications. The IoT applicationscould choose fog or cloud computing nodes forresponding to the resource requirements. Schedulingand load balancing algorithms are necessary forefficient and effective utilization of resources. Thispaper presents the survey of scheduling and loadbalancing algorithms in cloud and fog computingenvironment by using swarm-based optimizationtechniques

    Association between behavioural biases and investment decision-making: a meta-analysis

    Making sound investment decisions is not easy, and the field of behavioural finance warns of behavioural biases to avoid. While studies examining the relationships between behavioural biases and investment decision-making are aplenty, efforts to consolidate and analyse them collectively are scarce. Therefore, this meta-analysis aims to investigate the relationship between seven of the most prominent behavioural biases – as identified by past literature – present among individual investors and two aspects of investment decision-making, intuitive and rational. These seven biases were identified as overconfidence, herding, representativeness, availability, anchoring and adjustment, disposition effect and loss aversion. In total, 86 effect sizes from 36 studies comprising 7,615 participants from eight countries were analysed in a correlational meta-analysis. The findings show that overconfidence, representativeness, availability, and anchoring and adjustment biases were significantly and positively associated with the intuitive aspect of investment decision-making while loss aversion and disposition effects were significantly and positively associated with the rational aspect of investment decision-making. Herding was found to be not associated with both aspects of investment decision-making. Among the seven moderators examined, only age significantly moderated the relationship between availability bias and the intuitive aspect of investment decision-making, and the relationship between loss aversion bias and the rational aspect of investment decision-making. Gender, investing experience, education, continental difference, sampling technique and publication status did not display any significant moderation effects. The limitations of the present study as well as the implications for future research and practice are also discussed.Bachelor of Social Sciences in Psycholog

    BackgroundIn the context of an aging population, quality of life (QOL) is an important consideration for the well-being of the elderly. However, there is limited information on the QOL of the elderly in Myanmar. This study aimed to explore the risk factors for low QOL among the elderly in urban and peri-urban areas of the Yangon Region, Myanmar.MethodsA community-based, cross-sectional study was conducted among the elderly aged 60 years or older in two urban and two peri-urban townships in the Yangon Region from July to September 2019. A multi-stage sampling method was used to recruit study participants using a pre-tested questionnaire. A total of 616 (305 males and 311 females) elderly people were interviewed using a face-to-face interview technique. Multiple linear regression analysis was performed on the four domains (physical health, psychological health, social relationship, and environment) of QOL measured with the WHOQOL-BREF.ResultsIncome level and having intimate friends influenced the QOL scores of the elderly in all domains, while education level and marital status influenced psychological health, social relationship, and environment domains. Social interaction with neighbors increased the QOL scores for physical health, social relationship, and environment domains. Living in peri-urban areas was associated with lower QOL scores for physical health, psychological health, and environment, while participation in group activities increased QOL scores in these domains. Having comorbidities affected the QOL for psychological health and environment domains, while the frequency of going out affected physical health, and the frequency of religious performance affected social relationship.ConclusionResidential location, education level, marital status, income, comorbidities, social interactions with neighbors and friends, participation in group activities, and frequencies of going out and religious activities should be considered in planning and implementing programs for the elderly in Myanmar. Peri-urban development, strengthening healthcare and social security systems, and encouraging social interaction and participation in group activities play critical roles in improving the QOL for elderly residing in Myanmar

    Serological evidence indicates widespread distribution of rickettsioses in Myanmar

    Background Little research has been published on the prevalence of rickettsial infections in Myanmar. This study determined the seroprevalence of immunoglobulin G (IgG) antibodies to rickettsial species in different regions of Myanmar. Methods Seven hundred leftover blood samples from patients of all ages in primary care clinics and hospitals in seven regions of Myanmar were collected. Samples were screened for scrub typhus group (STG), typhus group (TG) and spotted fever group (SFG) IgG antibodies using enzyme-linked immunosorbent assays (ELISA). Immunofluorescence assays were performed for the same rickettsial groups to confirm seropositivity if ELISA optical density ≥0.5. Results Overall IgG seroprevalence was 19% [95% confidence interval (CI) 16–22%] for STG, 5% (95% CI 3–7%) for TG and 3% (95% CI: 2–5%) for SFG. The seroprevalence of STG was particularly high in northern and central Myanmar (59% and 19–33%, respectively). Increasing age was associated with higher odds of STG and TG seropositivity [per 10-year increase, adjusted odds ratio estimate 1.68 (p < 0.01) and 1.24 (p = 0.03), respectively]. Conclusion Rickettsial infections are widespread in Myanmar, with particularly high seroprevalence of STG IgG antibodies in central and northern regions. Healthcare workers should consider rickettsial infections as common causes of fever in Myanmar

    A first absolute chronology for Late Neolithic to Early Bronze Age Myanmar: New AMS 14C dates from Nyaung'gan and Oakaie

    Full text link
    Late prehistoric archaeological research in Myanmar is in a phase of rapid expansion. Recent work by the Mission Archéologique Française au Myanmar aims to establish a reliable Neolithic to Iron Age culture-historical sequence, which can then be compared to surrounding regions of Southeast Asia. Excavations at Nyaung'gan and Oakaie in central Myanmar have provided 52 new AMS dates, which allow the creation of Myanmar's first reliable prehistoric radiometric chronology. They have also identified the Neolithic to Bronze Age transition in central Myanmar, which is of critical importance in understanding long-range interactions at the national, regional and inter-regional level. This research provides the first significant step towards placing late prehistoric Myanmar in its global context
